    • Collapse dynamics for the discrete nonlinear Schrödinger equation with gain and loss 

      Fotopoulos, G.; Karachalios, N.I.; Koukouloyannis, V.; Vetas, K. ( Elsevier B.V. , 2019 , Article)
      We discuss the finite-time collapse, also referred as blow-up, of the solutions of a discrete nonlinear Schrödinger (DNLS) equation incorporating linear and nonlinear gain and loss. Such an extended DNLS system appears in ...

    • Dark solitons near potential and nonlinearity steps 

      F., Tsitoura; Z.A., Anastassi; J.L., Marzuola; P.G., Kevrekidis; D.J., Frantzeskakis ( American Physical Society , 2016 , Article)
      We study dark solitons near potential and nonlinearity steps and combinations thereof, forming rectangular barriers. This setting is relevant to the contexts of atomic Bose-Einstein condensates (where such steps can be ...
